A Guide to the Cost of Mold Inspections

April 3, 2014 By In Moisture Control Comments Off

If you suspect you have mold and you’re looking for a company to come in and perform an inspection there are a few things you should know.

1)      Looking for a free inspection? Be sure to find out what it is that you are getting for “free”.  If a “free” inspection means having someone with a flashlight come in and look around your home to tell you that you need professional mold removal then ask yourself did you really get an honest, comprehensive inspection? Chances are the only reason the inspection is free is to convince you that you need a service.

2)      If you are paying for a mold inspection, the price can range from approximately $100 – $500 (or more, depending on what type of inspection and what type of documentation you are provided with after the inspection).

3)       At a minimum, if you are getting a mold inspection make sure ….

  1. The inspector is a certified mold inspector
  2. The inspector is using an infrared (thermal imaging) camera AND a moisture meter AND a hygrometer.  Some companies use only a moisture meter or only an infrared camera.  It is important to know that you need BOTH of these tools to determine the scope and size of a potential mold problem.  Thermal imaging can identify temperature variations, but this doesn’t necessarily mean that the area is wet (for instance, limited insulation can be the cause of a cold zone in your home).  A moisture meter can measure the amount of moisture however, without the thermal imaging there is no way to determine size and scope of a problem other than scanning every surface of the home – which is nearly impossible and ridiculously time consuming.  Both of these tools need to be used together. The hygrometer measures the relative humidity (RH) in the air.  In order to have mold there needs to be a moisture and/or limited ventilation.  If the inspector is not using the right tools, they cannot determine whether or not you have a problem and the scope and size of the problem.
  3. If you are looking for samples to be taken, understand that air quality testing will provide you with the species and spore count of all airborne mold while samples (ie. bulk or tape lift samples) will only provide you the result on the sample.  Make sure the mold inspector understands your objectives and works with you to perform the right service based on your needs.  Gathering samples can become expensive so be sure to ask and understand what type of sampling is required.


In the end, if you suspect you have mold, and you’re paying for a certified inspector to inspect your home make sure you know what you are paying for.  Whether the inspection is free or not, the inspector must have the right tools and provide a comprehensive and honest assessment.
